"Sharpen" is a selection of levels and arrangements by Jordi Domènech, arranged by other authors.

I am grateful to the following authors your permission to include their arrangements in this collection: zhenying, Tian Lang, niwa, stopheart, Tui Leshan, David Holland, gyjgw, Přemysl Zíka, anian, laizhufu and Archanfel.

"Tour de France" is a beautiful puzzle of Eric F. Tchong, of which were made up to 11 arrangements. The first arrangement was mine, and then, in a few days, followed the arrangements of stopheart and anian. The last version was the h1, by anian + stopheart, and I think it's the most interesting (best moves/pushes: 1096/215; date: 2010.5.23). Apparently, the arrangement of Tui Leshan seems a simplification of h1, but there are some small changes that make it a version much more exciting and fun to solve.

Tui Leshan has built only a few puzzles, but his works are very elaborate and studied. I love your puzzles! In addition, he has a great aesthetic sense, which makes their puzzles and arrangements are small works of art.

It is perhaps the best arrangement I've seen in these last two years. Difficult, exciting, and fun to solve. A masterpiece. My rating difficulty: 7. Original level: 1,000,001 candlelights #32 april2014. I've arranged a little the map (left side).

A master arrangement. Like the arrangement of York Shen, this one of niwa only adds 2 boxes, but 484 more moves are needed to solve it. That's great! This puzzle has not been published, although I'm not sure. Niwa sent it to me by e-mail.

monry14 (diamond) and monry16 (elongated hexagon) are extensions of Sokoban Revenge #228. Is not sure whether in the first place François Marques added 6 boxes and then GRIGoRusha another 2 boxes, or vice versa. See also Remodel Club #51 (version monry16y) and #52 (monry16z+7, version by Marek Letrab with 14 stoned boxes more). In GrigrChallenge there are several remodels from monry16, most without solution: see gyjw0806c and following levels. Subsequently, York Shen posted on Yahoo! Sokoban three other remodels (with 2 more boxes).

This one and the next four levels are very hard. For specialists in chessboards within stepped structures.

Is an extension of yms12, inspired in the elongated hexagon from monry16 (which in turn is an extension of Sokoban Revenge #228). See also yms12c (Remodel Club #33)

Hard diamond with barriers of knots of boxes in both vertical and horizontal axes. The original level of gyjgw 火中取栗 (diamond of odd sides with 169 boxes) could be considered an extension of Sokoban Revenge #228, as well as also the next level of gyjgw 20050806.

This level was posted in the Chinese forum SuperSoko. I have given him the same external look that Sokoban Perfect #215.

The first version of this puzzle was published in Sokoban (1985, Sega) #74 and then in Sokoban Perfect (1989) #84. Inexplicably, this first version is very easy, and perhaps for this reason were made after two remodels: the first, in the same collection Sokoban Perfect #305 (by Masaki Ishino), and then another remodel in Sokoban Revenge #279 (by Kazuo Fukushima). The arrangement of Hir is one of the most beautiful that I know.

GRIGoRusha and zhenying have arrangements of similar difficulty, but perhaps this one of Howard is tighter. See also the elegant arrangement of Sokoban Revenge (1991) #231 by Takahiro Suzushima, with 4 boxes more.

This is the first level "two rows" of Sokoban and also the first in which they are used unequivocally rooms with sliding boxes. There are more than 30 arrangements of this classic level (see versions here), but I choose this one of York Shen, with a box more, which greatly increases the difficulty. I've slightly arranged the map (upper-left corner). The arrangement is also valid for the original level :)

Note of Jordi Domènech: The original puzzle of dzxmer + Jordi Domènech has been so modified that is unrecognizable. We must therefore consider this excellent puzzle as completely new and original, and in my opinion the author should be exclusively Tui Leshan.

Difficult! stopheart has extracted oil from a structure seemingly without possibilities.
See also MF8 29th Sokoban Competition, remodeled by stopheart, more difficult and with a structure very extended.

This is one of my favorite arrangements. Difficult storage. This arrangement is almost identical to the previous arrangement of GRIGoRusha (version c, 2004.1.7; see Remodel Club #58): the only difference is that in this version of zhenying has moved a box to I4. Is likely that zhenying did not know the earlier arrangement of GRIGoRusha.

Original level divided into two parts, and in which we must move the boxes from one part to another. It can be speculated that the author of this excellent level of old look is the same as that of the previous level (SP #302), since they were published consecutively in Sokoban 2 (1984).

It is the last level of Sokoban Perfect and one of the most difficult and arduous to solve in this collection. This version of York Shen change of place 9 goals, which obliges to use the storage area for storing some boxes on an interim basis, and forced to move the boxes by two rows of the storage area (exits out a box at the bottom, comes inside another box above).
